Support for personal mobility will be among the key factors for success in the competitive communications market of the future. This paper proposes enhancements to the personal mobility support capabilities of existing service architectures. The TINA service architecture is considered to be our starting point. The key issues in this paper are the following. First, the definition of the required...

To realize its promise of providing scaleable and optimal use of network resources, mobile agent technology must be integrated with non-mobile architectures (e.g., client-server) while taking into account the specific needs of applications. This paper introduces a general characterization of mobile agent applications that provides a framework for reasoning about such optimization issues. This f...

The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the co...

Mobile agent systems are a powerful approach to develop distributed applications since they migrate to hosts on which they have the resources to execute individual tasks. Existing mobile agent systems require detailed knowledge about these hosts at the time of coding. This assumption is not acceptable in a dynamic environment like a peer-to-peer network, where hosts and, as a consequence, also ...

To facilitate the design of large-scale, self-adaptive systems, we have developed the Port-Based Adaptable Agent Architecture. This distributed, multiagent architecture allows systems to be created with the flexibility and modularity required for the rapid construction of software systems that analyze and dynamically modify themselves to improve performance. This architecture provides user-leve...

The concept of an agent is increasingly used in contemporary software applications, particularly those involving the Internet, autonomous systems, or cooperation. However, with dependability and safety in mind, it is vital that the mechanisms for representing and implementing agents are clear and consistent. Hence there has been a strong research effort directed at using formal logic as the bas...

In this research, an architecture called the Agent-based Mobility Protocol (AMP) comprising a multi-agent system residing in both the mobile host(s) and the access networks has been developed for the purpose of enhancing mobility management in IP-based networks. The agent system on the mobile host was designed and subsequently built using an agent development platform called Agent Builder Pro. ...

Maintaining logical consistency in a knowledge base that receives asynchronous events from collaborative agents poses a challenge, due to multiple agent perspectives of the knowledge base. Facades and filters further complicate this problem by distorting the definition of consistent knowledge. Therefore, maintaining logical consistency of the knowledge base requires an infrastructure for handli...

In this paper we examine alternative means to exploit the advantages of code mobility, object-oriented design, and agent technology for high performance distributed computing. We describe an infrastructure for Problem Solving Environments based upon software agents.

In this paper we present the design and the implementation of Mobile-C, an IEEE Foundation for Intelligent Physical Agents (FIPA) compliant agent platform for mobile C/C++ agents. Such compliance ensures the interoperability between a Mobile-C agent and other agents from heterogeneous FIPA compliant mobile agent platforms. Also, the Mobile-C library was designed to support synchronization in or...
